Extended data
The rules of decimal reading are as follows:
1 and numbers within four digits can be read from the most significant bit in sequence. For example, 1987 can be read as 1987.
2. For numbers with more than four digits, first grade them by four digits from right to left, and then read out the numbers in each level and their horizontal names in turn from the advanced level.
No matter how many zeros there are at the end of a number, you can't read them. After classification, there is a zero at the end of any level, otherwise it will not be seen. When you need to read them, you can only read one zero, no matter how many zeros are in the middle or how many zeros are in succession, when you need to read them, you can only read one zero.
